MACHINE FOR MAKING BUTTONS AND THE LIKE Specification of Letters Patent.

Patented Mar. 13,1917.

Application filed May 9, 1913. Serial No. 766,530.

a subject of the Emperor of Austria-Humgary, residing at Deutsch-Beneschau, Ringplatz, in the Empire of Austrla-Hungary,

have invented certain new and useful Im-.

provements in Machines for Making Buttons and the like, of which the following is a specification.

This invention has for its object to provide an improved machine for the manufacture of buttons of metal and the like articles consisting of an upper and a lower part, or of an upper, lower, and middle part, of which each part is cut from sheet metal or the like. i I

In a machine according to the invention for the manufacture of buttons or the like articles each consisting for example of an upper part and a lower part, the pressing matrices for the lower article parts are mounted in a first slide and the pressing dies for the upper article parts are mounted in a second slide, said slides being movable apart from each other, to come opposite to the corresponding cutting dies and by being pushed toward each other the pressing dies of the one slide are placed directly over the pressing matrices of the other slide; the parts thus placed one above the other may be united directly by eans of pressure.

As the lower parts of the buttons are smaller than the upper parts, in order to avoid waste of material, the dies for cutting out the lower parts of the buttons must be spaced or pitched more closely together than the dies for cutting out the upper parts of the buttons and the pressing dies corresponding to the latter dies. Therefore the pressing matrices when they are under the cutting lock for the lower part of the buttons must have the same pitch as the cutting dies for the lower button parts in order to be able to take up the lower button parts directly from their cutting dies.

However, fter' the lower button parts have been so taken up and the slide carrying the matrices withthe lower button parts has been shifted to below the slides carrying-the pressing dies, the pressing matrices must have the same pitch as the cutting and pressing dies for the upper button parts in order to enable the pressing dies and the upper parts of the buttons hanging on the same,

to be introduced into the pressing matrices above the lower parts of the buttons contained therein, so that the upper button parts can then be united to the lower button parts.

According to the present invention, the

further arrangement is therefore made, that the pressing matrices which may be disposed in two or more rows, are made positively movable in the longitudinal direction, as well'as in the transverse direction, so that they can be adjusted to the pitch of the cutting dies for the lower button parts and also to the pitch of the pressing dies.

For the manufacture of buttons, each consisting of an upper, middle, and lower part, the arrangement may be such that a cutting block for the middle button'part is provided besides the cutting block for the lower button parts. The slide which carries the lower article parts may be movable underneath matrices for the manufacture of the middle article parts, in order to shift these middle article parts upon the lower article parts, whereupon by moving the slide for the lower article parts both the lower and middle article parts may be placed underneath the upper article parts and united together with the latter.

Two forms of the improved machine are illustrated by way of example in the accompanying drawings, in which Figure l is a longitudinal section of one embodiment of the machine for manufacture of buttons consisting of an upper and lower part.

Figs. 10 and 11 show a construction of a device for removing the complete buttons.

Figs. 12 and 13 show the elements of the buttons consisting of two parts, separately.

Fig. 1 1 shows the same in assembledposition.

As shown, the machine comprises an apparatus for punching or piercing and for cutting out the lower button parts, an apparatus for cutting out, drawing, and piercing the upper button parts, and an apparatus located between the two latter devices for uniting the upper and lower button parts to each other.

The plate strips (Fig. 2') of sheet metal or the like, for the upper and lower parts, are fed by means of feeding rolls 38 or in any other suitable manner, in the direction of the arrows between the cutting dies and the cutting matrices; preferably preliminarily to their introduction into the machine the strips are dished and if necessary pierced. The plate strip for the lower parts is introduced at 3% (Fig. 1) and the plate strip for the upper parts at 35 into the machine.

lhe apparatus for the manufacture of the lower button parts consists essentially of a mechanism for the preliminary pressing (see a. Fig. 2) and for the finishing punching, and. if necessary also for piercing the lower button parts (not shown). In front of this punching mechanism is a cutting block 34; with cutting dies 5 (Figs. 1 and The dies 5 cooperate with cutting matrices 5 and enter the same while cutting out the lower parts of the buttons. After the cutting operation the dies 5 thread the cut out, punched, and if necessary pierced, lower button parts onto the pins 3 of bolts 3 inserted through the pressing matrices 2. The pressing matrices 2 are deepened square as shown at 2 Fig. 1 or they are curved as shown in Figs. 6 audit). The pins 3 can also be employed for piercing the lower button parts. Preferably the pins 3 cooperate with holes in the cutting dies 5.

The lower parts of the buttons are cut out while the bolts 3 are moved upwardly by means of their driving member 11 in such a manner, that the pins 3 enter the holes of the dies 5 at the moment of the latter touching the. matrices 5f, whereupon the cut out lower button parts which are shifted upon the. pins 3 of the bolts 3, are lowered into the pressing matrices 2.

In accordance with the usual provision of four holes for sewing on the buttons, four pins 3?. may be provided on the bolts 3, entering four holes in the dies 5.

The apparatus for manufacturing the upper part of the button consists of a cutting block 35 with cutting dies 8 (Fig. 1), which coiiperate with cutting matrices 10 through which are guided drawing dies 9, which convey the cut-out upper part of the button into the matrices 10 and thereby eifect the turning over of the edge. Above the cutting block 35 is guided the slide 6 (Figs. 1, 7 and 8) which, in the example shown, is movable toward and above the slide 1, carrying the pressing matrices 2 (Fig. 1). In the slide 6, the pressing dies 7 are mounted on a plate 16. Through the press dies 7 pass .the pins 11 of the piercing dies 11, which,

in connection with corresponding holes in he drawing dies 9, pierce the upper parts of the buttons (Figs. 1 and 8) and receive them threaded on tothe pins 11 In order to prevent the return of the piercing dies 11, when piercing the upper button parts, stops are provided, for instancescrews 7 5, which prevent the plates 18 and 19 in which the piercing dies 11 are inserted and held tight, from going backward (Fig. 7).

For uniting the upper and lower button parts which are cut-out by the cutting dies 5 and 8, and pierced by the piercing dies 3 and 11, the two slides 1, 6 are mounted so as to be movable toward each other, whereby the lower button parts contained in the pressing matrices 2, and the upper button parts, threaded on the pins of the piercing dies 11, are located adjustably above each other (Fig. i).

As the lower button parts which are stamped close to each other are smaller than the upper button parts, provision is made in the machine for allowing of adjustment of the lower button parts to the pitch of the upper button parts. According to the invention this is effected by the pressing matrices 2 being made adjustable in the longitudinal direction, and in the case of multiple row arrangements also in the transverse direction, of the slide, and in such a manner that when the slide is moved, they are positively adjusted to the pitch of the pressing dies 7 in the longitudinal and transverse directions.

In the example shown, the pressing matrices 9. are arranged in plates 1 lhe one matrix 2 may for instance be fixed, while the other matrices are mounted in the plates 1% and are mo able therein in the longitudinal direction (Figs. 1 and lhe plates 14s carrying the pressing matrices 2 are mounted on the slide 1 and are movable in the transverse direction (Fig.

The adjustment of the matrices 2 to the pitch of the pressing dies 7 in the longitudi nal direction is effected by means of fixed projections 12 (Figs. 1 and 5) during the forward. pushing of the slide against which projections the press matrices which are arranged behind each other are, caused to in determined their driving member strike successively, being thereby adjusted distances from one another. When the slide is pushed back, the press matrices 2 are again pushed together in the longitudinal direction to the pitch of the cutting dies for the lower button parts by means of projections 36 (Fig. 1).

The adjustment in the transverse direction of the slide, in the case of a two row arrangement of the press matrices, may be effected by means of a fixed key 13, and in the case of a multiple row arrangement by means of several such fixed keys 13 which may be secured with a cross piece 13 (Fig. 1) to the slide guide 76. lVhen the slide moves, the keys 13 engage between the plates 14 that carry the pressing matrices 2. whereby the pressing matrices are forced apart in rows. When the slide returns, the plates 14 are pushed together again by means of guides 37, which for this purpose converge one toward the other (see Fig. 5).

The method of working of the machine is as follows In the sheet metal strip 4 (Fig. 2) the lower button parts a are preliminarily pressed by means of a punch, then completely dished, and, if necessary, pierced. The dished, and if necessary pierced, lower button parts are, in consequence of moving the sheet strip 4 (for instance by means of rollers 38, Fig. 2), adjusted over the pins 3 of the bolts 3 and below the cutting dies 5. By means of the cutting dies 5 and the cutting matrices 5 the lower button parts are cut from the plate strips 4 and threaded on to the pins 3 of the raised bolts 3 by any suitable means, for example with aid of rams or plungers 41 (Fig. l), suitably acted upon or, if the lower button parts were not previously pierced, they are pierced by the pins 3 of the bolts 3 and simultaneously threaded on.

The cutting dies 5 are then raised and the bolts 3 with the threaded-on lower button parts are lowered into the pressing matrices 2 (Figs. 1 and 5). In order to insure that the bolts 3 shall move down together with 41, the bolts are provided at their lower ends for instance with heads, which are guided in a T-shaped rail 40 (Figs. 1 and 6), thus insuring that all the bolts are pulled member 41 is lowered.

At the same time, the upper button parts are cut from a second sheet strip introduced at 35 by means of hollow cutting dies 8 coacting with cutting matrices 10. By the following upward movement of the drawing dies 9, the cut out upper button parts are driven through the matrices 10 which thereby act as drawing dies and whereby the edges of the upper button parts are bent over. By a further upward movement of the drawing dies 9, the bent-over upper butdownward when the from returning too far ton parts are pressed against piercing pins 11 provided on dies 11, (Fig. 1). Through the cooperation of the pins 11 of the dies 11 with corresponding holes in the drawing dies 9, the upper button parts are then pierced. The dies 11 are inserted intopressing dies 7 mounted in a slide 6. By a powerful pressure of the contoured ing dies 9 on the contoured press dies 7, the upper button parts can be contoured. The completed upper button parts remain threaded on the pins 11 of the dies 11 after the return of the drawing dies 9.

As soon as the drawing dies 9, as well as the bolts 3 have returned, so that the slide 1 and slide 6 no longer engage with the cutting block and the drawing dies, the two slides are moved toward each other and adjusted one above the other. During the movement of the slide 1, the plates 14 are driven apart from each other action of'the key 13, in such a manner, that at the end of the stroke of the slide the pitch (Z of the pressing matrices 2 (Fig. 5) is equal to the pitch of the pressing dies 7 By the action of the projections 12, the pressing matrices 2 which are movable longitudinally in the plates 14 are adjusted at such a distance from each other longitudinally, that the pitch f of the pressing matrices 2 (Fig. 5) is equal to the pitch of the pressing dies At the end of the stroke of the two slides the lower button parts are accordingly located exactly under the upper button parts.

The plate 16, in which the pressing dies 7 are secured by means of nuts 17 (Figs. 7 and 8), is guided with projecting ends in grooves 43 of the ram 15, when the slide is moved to the left (Fig. 7). By the clownward movement of the ram 15 the pressing dies 7 and also the piercing dies 11 which are fixed in the plate 18 and secured by a plate 19 secured to plate 18 by screws) are moved downward. The plate 18 is arrested in its downward movement (for instance by means of bushes 44 on the screws 7 5 (Fig. 1) before the pins of the piercing dies 11 come in contact with the pins of the bolts 3, so that on the further downward movement of the pressing dies 7, the upper button parts are removed from the piercing dies 11 and threaded on to the pins of the bolts 3, on

drawthrough the which are the lower button parts, and afterward their edges are bent over the lower button parts. The ram 15 now returns to gether with the pressing dies 7 and pierc ing dies 11.

In order to prevent the plates 18 and 19 from returning too far, stops are provided, for instance screws 75 Figs. 1 and 7 The plate 16 and pressing die 7'are prevented by the shoulders of the bushes 44 in the example shown.

The completed buttons which hang on the pins of the bolts 3 are raised from the press 11) .is provided in the space under member 22 to a lever The removing device 20 is and piercing the lower ing matrices 2 (Fig. (3) by raising the bolts 3.

For taking off and removing the complete buttons, removing device 20 (Figs. 10 and the rain 15, which, in the example shown, is pivotally mounted in a movable fork 21 (Fig. 2). lhe fork 21, which is movably guided in the easing, is connected by means of a connecting This lever 23 is rotatable about the bolt roller 25, which works for instance in a camgroove 26, whereby the removing device is moved backward and forward positively. moved under the raised buttons (Fig, 10) whereby upon the downward movement of the pins 3 the buttons are removed from the same through the action of the removing device and then lie on the latter. The removing device is now pulled back and thereby a lever 27 is knocked against a nose 28, whereby the re moving device is swung upward, and the buttons are conveyed away along the sloping surface formed by the removing device. The slides 1 and 6 are now again pulled back into their original positions and the described working cycle is repeated.

In order to prevent the plate 16 with the pressing dies 7 from moving downward in the commencing position of the slide 6, two rails d5 (see Fig. 1) are provided in the slide casing 80 upon which rails :5 the plate 16 lies with its projecting end.

In Fig. 9 a modification of the machine is shown for the manufacture of buttons composed of upper, middle and lower parts. To the left is provided a device for dishing button parts which device is constructed and arranged in the same manner as before described with regard to Fig. 1. The slide 1 moves, if shifted to the right, first below a second cutting block 48, which cuts out the middle button parts in exactly the same way, as this is done with the lower parts in the modification shown in Fig. 1. The middle parts are taken up by the piercing pins 3 of the bolts 3', above the lower button parts, as may be seen in Fig. 9. Thereupon the bolts 3' are lowered together with the lower and middle button parts reposing upon their piercing pins 3 until these button parts are brought to rest in the pressing matrices 2.

The device for upper button parts is side of the drawing and is constructed in the same manner as in Fig. 1. Instead of the pins of the piercing dies there is a drawing die 49 rigidly connected with the die 11 and passing through a hole in the pressing die 7 as shown in the drawing and piercing a hole into this button part. Both slidesl and 6 are moved to lay the one above the the manufacture of the disposed on the right and carries a other, in the same manner as described with regard to the modification shown in Fig. 1. Thereupon the upper button parts are shifted upon the middle and lower parts by lowering the pressing dies 7 and the drawing dies l9; by a continued downward movement of the pressing dies the outer edge of the upper button part is bent over the lower button part, whereupon the buttons are finished and are removed in the manner before described, by the removing device.

The slide 1' together with the pressing matrices 2' is shifted thereupon to the left into its starting position while the slide (3 is moved to the right also into its starting position.
